The artificial electron acceptors cannot be directly reduced by the enzyme. Their reduction requires the presence of phenazine ethosulfate or phenazine methosulfate. Electrons are transferred from an oxidizing substrate to the PQQ moiety, and protons are released into the cytoplasm. The reduced PQQ moiety donates electrons to cytochrome c one after the other, yielding the semiquinone form of PQQ
